Install SIM cards
To install SIM cards:
1. On the TX54 front panel, use a Philips screwdriver to remove the SIM slot cover.
2. For high-vibration environments, apply a thin layer of dielectric grease to the SIM contacts.
Note If the TX54 device is used in an environment with high vibration levels, SIM card contact
fretting may cause unexpected SIM card failures. To protect the SIM cards, Digi strongly
recommends that you apply a thin layer of dielectric grease to the SIM contacts prior to
installing the SIM cards. See
Apply Dielectric Grease over SIM Contacts for instructions.
3. Insert the SIM card(s) into the SIM sockets in the positions shown on the SIM gasket:

4. After all SIM cards are in place, replace the SIM slot cover.
Apply Dielectric Grease over SIM Contacts
Note Digi recommends using either …the Loctite® LB 8423 Dielectric Grease or Synco Lube® Silicone
Dielectric Grease.
1. Use a sheet of paper or cardboard over the area where you intend to work.
2. Use isopropyl alcohol and a cotton-tipped applicator to gently clean the SIM contacts. Using
isopropyl alcohol requires a well vented environment. Demineralized water can also be used as
an alternative.
